With the aim of enhancing the efficiency of near infrared (NIR) organic light-emitting devices (OLEDs), two new triphenylamine-functionalized NIR iridium(III) complexes by covalently attaching the functional moieties (tBu and F) complexes (tBuTPA-BTz-Iq)2Irpic and (FTPA-BTz-Iq)2Irpic were designed and synthesized (TPA = triphenylamine; BTz = benzotriazole; Iq = isoquinoline). It was found that compared to their parent iridium complex (TPA-BTz-Iq)2Irpic, the addition of either butyl or fluorine groups into the ligand play an important role in improving the optophysical and electroluminescent characteristics. In solution-processed phosphorescent OLEDs, the (tBuTPA-BTz-Iq)2Irpic-based devices achieved a maximum external quantum efficiency (EQEmax) of 0.66% at 716 nm, while the (FTPA-BTz-Iq)2Irpic-based devices achieved an EQEmax of 0.48% at 710 nm. The EQEmax level is 2.28 or 1.65 times higher than that in the (TPA-BTz-Iq)2Irpic-based devices (0.29% at 712 nm), respectively.

The new process is characterized in that pyridine 1-oxides of the formula II STR2 are reacted with a chlorine-containing phosphoric acid derivative from the series of the chlorophosphoric esters and chlorophosphoramides in the presence of an inert organic solvent and in the presence of an acid acceptor at temperatures between -20 C. and 200 C., and the resulting product is separated further, if appropriate. Compound (I) is known as an intermediate product for medicaments (cf.DE-A 2,812,585) or for insecticidel nitromethylene derivatives (cf. EP-A 163,855).

Non-oxidative photocyclization of the enamides (2c,d,e) in benzene at low temperature afforded a new type of the lactams (4c, d,e) and ( 8 ) which have a comnon dihydrobenzene moiety and were readily transformed into the corresponding dehydrolactams (5c,d,e) and (7), thus firmly established the reaction course of photocyclization of these enamides under non-oxidative condition.

In some cases, the catalyzed mechanism may include additional steps.In a article, 1532-97-4, molcular formula is C9H6BrN, introducing its new discovery.

N-alkyloxycarbonylmethyl-1,2-dihydroisoquinolin-4-carboxylic acid derivatives 7 a-c were synthesized as new carriers for brain specific delivery. The design of the carrier systems are based on sequential hydrolysis at the acetic acid ester group linked to dihydroisoquinoline nitrogen followed by ring oxidation and formation of quaternary isoquinolinium derivatives which are then hydrolyzed to release the drug. Once the carrier system is administered, a sequential enzymatic process will take place resulting in significant increase in its rate of oxidation, the key factor in brain specific delivery. The chemical stability of the synthesized carrier system was investigated in aqueous buffer solutions and ferricyanide reagent and proofed to be quite stable against hydration and oxidation during formulation and storage. Furthermore, enzymatic stability was also investigated in 80% human plasma and 20% rabbit brain homogenate. Both oxidation and hydrolysis were found to take place; however, hydrolysis was the major route. In vivo distribution of the ethyl ester derivative 7 b was studied in rats and showed that the concentration of the quaternary product is increasing in the brain and cleared from blood with time.

2-(2-Acyl-1-tetrahydroisoquinolyl)cycloalkane-1,3-diones were obtained by the reaction of 3,4-dihydroisoquinolines with 3-acyloxy-2-cycloalken-1-ones.It was established by spectroscopy that the synthesized compounds are fully enolized both in solution and in the crystalline state.The data from the 13C and 1H NMR spectra indicate that in solution in deuterochloroform the synthesized compounds exist in a single conformational form, stabilized by an intramolecular hydrogen bond between the enolic hydroxy group and the amide carbonyl.It was established by a series of experiments on the nuclear Overhauser effect in the 13C and 1H NMR spectra that the acyl residue in these compounds is pseudoequatorial, while the cyclohydroxyene fragment is in the pseudoaxial position in relation to ring B of the tetrahydroisoquinoline fragment.

The synthesis and stereochemical characteristics of pyrrolidino-, isoquinolino- and indolo-enaminones 2-11 are reported. The inhibition of cyclooxygenase was determined in a bovine thrombocyte intact cell assay and that of 5-lipoxygenase using intact bovine polymorphonuclear leucocytes. Except compound 2c? which is a well-balanced dual inhibitor of both enzymes, all other enaminone derivatives are weak inhibitors of both cyclooxygenase and 5-lipoxygenase. Structure-activity relationships of the enaminones in relation to known anti-inflammatory drugs are discussed. Johann Ambrosius Barth 1998.

A straightforward synthesis of C3-symmet:ric, imidazole-containing, macrocyclic peptides with different binding arms is presented, The chirality of the backbone and the selection of adequate receptor arms make these systems highly selective receptors for alpha-chiral primary organoammonium ions. Furthermore, the receptors have the ability to discriminate between enantiomeric guests with selectivity ratios of up to 87:13, The binding constants and the selectivity ratios were estimated by standard 1H NMR titration techniques in CDCl3.

The influence of electron-withdrawing and electron-donating substituents (nitro, nitrile, chloro, bromo, methoxy or amino) on 1,3-difluorobenzenes in their palladium-catalysed direct C2 arylation has been explored. With most substituents, the reaction proceeds nicely using air-stable palladium catalysts (0.5-2 mol-%) and KOAc/DMA. In general, very regioselective C2-arylation was observed. Moreover, a variety of substituents on the aryl bromide coupling partner (ester, acetyl, formyl, nitro, nitrile, trifluoromethyl, chloro, fluoro or methyl) was tolerated. Palladium-catalysed direct arylation of 4- or 5-substituted 1,3-difluorobenzenes allows the synthesis of 2-arylated 1,3-difluorobenzenes in one step. This regioselective C2-arylation proceeds with air-stable palladium catalysts and KOAc/DMA. Both electron-withdrawing and electron-donating substituents (chloro, bromo, methoxy or amino) on the 1,3-difluorobenzenes were tolerated. Copyright

Synthetic Route of 1125-80-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1125-80-0, Name is 3-Methylisoquinoline, molecular formula is C10H9N. In a Article，once mentioned of 1125-80-0

A microbial process using the fungus Absidia repens ATCC 14849 is described for the oxidation of 2-methylquinoxaline to 2-quinoxalinecarboxylic acid. A campaign consisting of three 14000-L runs produced 20.5 kg of the acid with a 28% overall yield. The bioconversion gave a lower yield compared with a three step chemical synthesis (35%), but was carried out in one pot, and avoided safety issues with a di-N-oxide intermediate. Although successfully scaled to produce kilograms of 2-quinoxalinecarboxylic acid for synthesis of a drug candidate, the A. repens bioconversion is unsuitable for further scale-up due to low product concentration (?1 g/L). A second microbial process using Pseudomonas putida ATCC 33015 is also described for the oxidation of 2-methylquinoxaline. The P. putida bioconversion gave an 86% in situ yield at 8-L scale and yielded a product concentration approximately 10-fold greater than that of the A. repens bioconversion.
